public class RedirectFollowEditor

extends HttpEditor

This editor Meg follows all redirects (HTTP 301 & 302 response codes) by using the FetchUrl API. It also determines the BASE url and fills in all relative links. This last step is necessary otherwise the base would be inferred incorrectly by the browser after a redirect.

Here are some cases where you might find this functionality useful: (a) you're writing a very simple lightweight browser and want some of the functionality to be implemented as a WBI plugin (b) you the client is down a slow link and you want to avoid the added latency of the round-trip incurred by the redirect.
